To all whom, it may concern.-

Be it known that I, JOHN W. WEEKS, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Gas- Pressure Regulators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to automatic pressure-regulators, and has for its primary obj ect to provide a simple, practical, and ineX- be readily connected to the main pipes of the regular illuminating-gas-supplying system of a dwellinghouse or other build' g to automaticallyregulate the pressure of gas as it is supplied to the burners therein.

The usual method of piping a house for gas is to have the pipes so arranged that by the ordinary city-pressure a suificient amount is supplied so that all of the burners maybe used at once. Therefore when all of the burners are not in use there is an excess of pressure on' those that are lighted. Consequently the gas blows and is wasted.

By the use of my device the pressure of the gas is automatically regulated, so that only the necessary amount is supplied whether one burner or all are in use.

The invention is fully set forth in this specification and more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a sectional side elevation of the device, showing the operating mechanism. Fig. 2 is a sectional end view of the device. Fig. 3 is a plan view of the device with the gasometer removed to better show the valve connections. Fig. 4 is a detail perspective view of the frame in which the valve and its connections are'mounted. Fig. 5 is a detail perspective view of the valve.

Referring to the drawings, at I is the valvecasing, semicircular in its cross-section, as shown at 2 in Fig. 2. The casing is drawn out at both ends 3 and 4, one end being tapped for the reception of the inlet-pipe 5 and the opposite end tapped forIthe outlet-pipe 6.

The base of the casing 1 broadens out as it extends upward into a circular or tubular form, as shown at 7. Outside of this tubular portion 7 is another tubular portion or shell 8, larger in diameter than cured to the base shoulder 9.

portion 7 and seof said portion 7 at the These two tubular portions 7 and 8, thus arranged, form a narrow annular water-tight chamber 10 between them. This chamber 10 is filled with mercury and is for the purpose of receiving the lower portion of the inverted-cup-shaped gasometer 12, that fits loosely therein.

' At 13 is a frame designed to fit into the base of the casing. This frame is made separate, so that the valve 14 and its connection may be mounted therein outside of the casing and then dropped into place in the casing and secured by the two screws 15 15. It is a great convenience to be able to assemble the working parts complete before they are in serted into the casing. The construction is thereby simplified and the cost is reduced.

The valve 14 is pivotally mounted to swing on a pair of arms 16, which arms are pivoted at their upper ends to the ear 17 on the valve and at their lower ends to the frame at 18. The valve-seat is preferably formed of a short tube 19, forced into the inlet end of the casing and extending outward a short distance therefrom to form a finished seat to receive the face of the valve 14 when it is forced up against the same.

At 20 is a pair of flat arm connections pivoted at one end to the trough member at 21 and at their opposite ends at 22 to the con nection 23. This connection 23 is also pivoted at one end at 17 to the valve. Pivoted at the point 22 to both of these connections 20 and 23 is the connection 24, which latter connection is also pivoted at its upper end to the adjustable eyebolt 25, suspended through the head of the gasometer. This bolt 25 is threaded on one end and has two adjustingnuts 26 and 27 screwed thereon, one being on the inside of the gasometer-head and one on the outside thereof, and by these nuts the said bolt may be adjusted either up or down to regulate the length of the connection 24, and consequently the throw of the valve, and by these nuts said bolt may be locked in the desired position.

The operation of the device may be further described as follows: My improved regulator is preferably iiiiserted into the main su l i e o t e or inary gas-su 8 rsteffi bla t vsen the meter and the burn ei sl T he gasometer 12 rises and falls freely in the annular groove or chamber 10 and is sealed by the mercury that fills the groove. This gasometer is connected to operate the swinging valve 14 through the levers 20, 23, and 24, which levers form a tOggleomt to more easily operate said valve against the pressure of gas. When all of the burners are closed, the

as-pressure naturally rises in the pipes and forces up the gasometer, and the valve 14 is carried over against its seat and a further supply of gas is shut off. When one burner is lighted, the gasometer will fall slightly and open the valve just enough to admit the proper quantity of gas to flow in and supply that burner with the required pressure. When two burners are lighted, the gasometer falls a little lower and admits a greater quantity, and so on until all of the burners are lighted, When the valve will be opened sufficiently to supply them. Small weights 28 are placed on the gasometer and by adding to or taking from the same the pressure may be nicely regulated to supply either one or any number of burners with the required pressure. The gasometer is closed in on top by the cap 29, which fits over the upper end of the tubular portion 8.

It will be noted that by pivoting the valve 14 in its swinging support the same has a Wiping action on the valve-seat 19 as it moves toward or away from the latter, thereby preventing the corrosion of said valve-seat or the accumulation offoreign substances thereon. This wiping action thus insures a valve-seat, and consequently a tight joint between the valve and its seat.

The device is very practical and efficient and by its use the gas-lights are nicely regulated to burn steadily and without the usual blowing and waste caused by burning lights with an excess of pressure.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An automatic pressure-regulator comprising a casing having an inlet provided with a valve-seat, and an outlet, a swinging member pivotally supported in the bottom of said casing adjacent said valve-seat, toggle members connected to said swinging member, a valve pivoted to the free end of said swinging member, and having a wiping contact with said valve-seat, a gasometer fitting .over the top of said casing, and a connecting member extending from said toggle members to said gasometer.

2. An automatic pressure-regulator com prising a casing provided with an inlet and an outlet and provided with a contracted semicircular bottom, a frame fitting in said bottom, a swinging member pivoted at one end of said frame, a togglejoint carried by said frame and connected to said swinging member, a valve pivoted on the free end of said swinging member, a gasometer fitting over the top of said casing, and a connecting member extending from said gasometer .to said togglejoint.

3. An automatic pressure-regulator comprising a casing provided with an inlet and an outlet, said inlet being provided with a valve-seat, and an upper annular extension, I

said casing being also provided withan annular shoulder spaced apart from said-extension, a shell orcasing fitting in said shoulder and surrounding said extension, whereby an annular space or chamber is formed, a gasometer working in said space or chamber, a swing ingmember pivoted in the bottom of said casing, adjacent said valve-seat, a valve pivotally mounted on the free end .of said swinging member, and having a wiping contact with said valve-seat, and'connections between said,

gasometer and said swinging member.

4. An automatic pressure-regulator comprising a casing provided withan inlet and an outlet, said inlet being provided with a valve-seat, and also with an annular chamber, a gasometer arranged to work in said channel, an independent frame mounted in the bottom of said casing, means forsecuring said frame in position, a swinging member pivotally mounted in said frame, adjacent said valve-seat, a valve pivotally mounted on the free end of said swinging member, and

havin a wiping contact withsaid valve-seat, a togg e-joint carried by. said frame and also connected to the free end of said swinging member, and a connection between said gasometer and said toggle-joint.

In testimony whereof I aflix my signature in presence of two witnesses.
